BURNER.

SPECIFICATION forming part of, Letters Patent No. 738,290, dated September 8, 1903.

Application filed Marcii 21, 1903. $eria1No. 148,812. (No model.)

To aIZZ whom it may concern:

Be it known that I, JESSE T. B'URR, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Burners; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it apper tains to make and use the same.

My invention relates to burners adapted to be used more especially for natural gas; and the invention consists in a burner constructed and combined in its parts, substantially as shown and described and particularly pointed out in the claims.

Figure 1 is a plain elevation of one of the several forms in which my burner may be constructed, having an outside cam-ring, and Fig. 2 is a vertical sectional elevation thereof. Fig. 3 is a vertical sectional elevation of a modification of the burner with an inside cam-ring.

In these as well as in other possible forms of the invention (not shown) the main and essential element is an adjustable burner-cap or portion G, a body B, and a ring between said parts having cam-surfaces for making adjustments. Such adjustment is very desirable because it enables each individual burner to be regulated according to the pressure of gas in a given place, as well as accord ing to the volume or amount of gas it is desired to consume at any time. Now it is obvious that various modifications of the invention employing rings having cams might be shown to afford such adjustment orrelation of cap Cto bodyB, and while I have attempted herein merely to illustrate two forms of construction serving my purpose, other forms equally good and effective might be shown and are regarded as within the spirit and scope of my invention, my idea being the adjustment of the cap or like part on a burner of this kind by a cam-ring capable of a very fine adjustment.

Referring now again to Figs. 1 and 2, it is seen that body Bis of substantially cup shape and has a reduced inner rim portion 2 about its top, at the base of which and on the enlarged portion or shoulder 3 thereof is seated a ring E, which has two or more cams 4., upon which rest the inclined surfaces 5 of lugs 0 upon cap C. These lugs come immediately outside of rim or flange 2 of the body and have set-sorews 7 by which the cap is fixed in any desired position, according to the elevation of the cap and the volume of gas to be consumed and which issues through the nar row opening or space 8 between cap and body. It will be observed also that cap 0 extends outward beyond body B all around and is curved downwardly about its outer edge 9, so as to give a downward deflection to the gas at this point, where combustion begins, and which helps to promote admixture of the gas as it issues and impinges against the overhanging edge 9 of the cap. The cap has a downward curvature at its edge for this purpose.

In the modification, Fig. 3, body B is of substantially cup shape, with rim 1) about its outside and a seat 11 for a cam-ring inside, While lugs c on cap 0 come inside said rim and rest upon cam-ring D, which itself rests on a11- nular seat or shoulder 11. The said lugs c are shaped to seat upon cam-surfaoes (Z on said ring. A set-screw 12 is employed to secure the cam-ring in its rotary adjustments after adjustment has been made.

It will be understood that pipe P is a supply-pipc from a mixer, (not shown,) so that the gas flowing through this pipe into the burner has already received the necessary admixture of air.

Body 3 is in all the views here shown open across its top, and the cap overlaps and extends beyond its top edge all around evenly. In Fig. 3 the edge of the cap is inclined or beveled to give a flaring effect upward and outward, as is also the edge of rim 1) correspondingly.

I can invert the device and have a very perfect superheater. In that case I close the top and tap the bottom, which simply reverses what is shown, but is practically the same thing in effect.

IVhat I claim is- 1. A gas-burner having a hollow body open across its top, a cap extending outward beyond said body all around and a horizontallyrotatable cam-ring for adjusting the elevation of the cap, substantially as described.

2. The body of the burner and the cap, and

a cam-ring between said parts to fix the elering can be rotated and the elevation of the IO vation of the cap in respect to the body, and cap fixed, and means to secure the cap to means to secure said cap on said body against said box, substantially as described.
